4. Transfusion of Blood Product

5. History: 1920:Sodium citrate anticoagulant(10 days storage) 1958: Plastic bag of transfusion 1656: Initial theory and methods (UK) 1665: Dog to dog transfusion 1667:Animal to human transfusion(20 times)by Denys ;one case expired with anaphylaxis in third transfusion 1975: Blood banking and blood products

6. Major Indication for Blood Product Transfusion: Restore Blood Volume Maintain oxygen carrying capacity Maintain hemostasis Maintain leukocyte function

9. Blood Donors: Healthy volunteers Healthy volunteers 17 years Usually over the age of 17 years 110 pounds At least 110 pounds in weight. detailed medical history Each donor is initially screened through a detailed medical history

14. Blood Test: 1. Antibodies to HIV-1 and HIV-2 (AIDS), 2. Antibodies to HBc produced during and after infection with Hepatitis B Virus 3. Antibodies to HCV produced after infection with the Hepatitis C virus 4. Antibodies to HTLV-I/II produced after infection 5. Antibodies to HBsAg produced after infection with Hepatitis B 6. HIV-1 p24, a test for the HIV (AIDS) antigen 7. For blood type (ABO) and Rh factor 8. Tp, the agent that causes syphilis 9. ALT,Coombs,CMV 10. NAT

15. NAT (Nucleic Acid Testing): A new technology that can detect the genetic material of Hepatitis C and HIV.

22. Packed CellPlatelet ConcentratePlasma

23. Red Blood Cells: 40-50% Blood Volume Oxygen carrying Store till 42 days in 4-8  C The most commonly blood product

24. Platelets: Platelets account for a small percentage of whole blood volume Control bleeding multiple doses Often transfused in multiple doses stored at room temperature Platelets must be stored at room temperature five day Only a five day shelf life

27. Plasma: A watery substance A watery substance in which proteins that trigger blood clotting mechanisms are suspended. raw material Plasma is used as a raw material “ Fractionated ” “ Fractionated ” into its different protein components Factor VIII, and other factors up to one year Plasma can be stored frozen for up to one year

30. Contraindication of Blood Product Transfusion No Absolute Indication of Blood Product Transfusion

31. The most important factor for blood transfusion: Patient’s clinical condition (Not a laboratory results)

32. Questions that need to be asked prior to a blood transfusion? patient’s condition 1)Will the patient’s condition be improved by a blood transfusion? alternative therapies 2)Do any alternative therapies to blood transfusion exist? benefit 3)Do the benefit of a blood transfusion outweigh the potential risks?

33. Criteria for viability of red blood cells on the final day of storage in particular anticoagulant: 1)A mean of 75%survival 24 hours after transfusion 2)Less than 4% hemolysis 3)Normal survival after 24 hours

34. Indication for Packed Cell Transfusion in Ill Patient who Admitted in ICU: HCT<35-40% In Neonate HCT<40-45%

35. Hct( Post transfusion) = (BW*80*Hct-P)+(R-Vol.*Hct-C) BW*80 BW=Body Weight(Kg) Hct-P=Pretransfusion Hematocrit R-Vol.=Volume of red cell transfusion Hct-C=Hematocrit of transfused cell

36. Whole Blood ( <10 Days Storage): Whole Blood ( <10 Days Storage): cardiac surgery Those undergoing cardiac surgery Acute blood loss Acute blood loss ( no suitable product is present)

38. Shelf Life of Red Cell Products: CPD: 21 Days CPD-A: 35 Days Adsol(AS-1): 42 Days Nutricel(AS-3): 42 Days Optisol(AS-5): 42 Days

39. Red Cell Products: Whole Blood Fresh Whole Blood Frozen Deglycerolized Packed Cells Packed Cells Leukoreduction of Red Cells Irradiation of Red Cells

41. Whole Blood: Massive Transfusion (Cardiac surgery) Exchange Transfusion

42. Fresh Whole Blood: Non refrigerated fresh blood administered by exchange transfusion within 4-6 hours of drawing can deliver a sufficient number of viable leukocytes. The dose required is 1x10  9 PMN/Kg (1½Blood Exchange Transfusion)

43. Frozen Deglycerolized Packed Cells Antigen matched transfusion Neonatal transfusion

44. Filtered Red Cells: Prevention of febrile non hemolytic reaction

46. Irradiation of Red Cells: Neonates Immuno-compromised recipients

48. Massive Transfusion: Replacement of more than one blood volume within 6 hours period

49. Causes of Massive Transfusion: Neonatal exchange transfusion Cardiac surgery Trauma Liver transplantation

50. Complications of Massive Transfusion: Citrate toxicity Alkalosis Hypokalemia Coagulopathy

51. Indication for Packed Cell Transfusion in Ill Patient who Admitted in ICU: HCT<35-40% In Neonate HCT<40-45%

54. Criteria of Platelet Transfusion: Platelet count<5,000-10,000/  L Minor or Major surgery< 30,000-60,000/  L Brain or Ophtalmic Surgery<50,000  L Massive Transfusion<30,000/  L
